Early results of negative pressure wound therapy in treatment of chronic wounds

Abstract

Background: Chronic wounds may affect only the epidermis and dermis, or they may affect tissues all the way to the fascia. Chronic wounds seem to be detained in one or more of the phases of wound healing. For example, chronic wounds often remain in the inflammatory stage for too long. Aim of the work: to assess the effect of negative pressure wound therapy in management of chronic wound. Patients and Methods: This is prospective study was conducted on 30 Egyptian volunteers participated; they were 20 males and 10 females, between the age of 18 and 70 years. This study was conducted from July 2017 to July 2018 at Ain shams university specialized hospitals and Alexandria armed forces hospital. Results: VAC therapy, together with periodical surgical wound debridement and specific antibiotic therapy, could be helpful to promote and accelerate wound healing of foot lesions after restoration of an adequate distal blood flow through surgical revascularization or angioplasty. Conclusion: Negative-pressure wound therapy (NPWT) devices are designed to apply controlled suction to a wound bed at continuous or intermittent pressure settings to stimulate wound closure. Negative pressure can result in numerous alterations in the wound environment, including removal of excess exudate containing high concentrations of proteases and inflammatory cytokines, stimulation of senescent cells, mobilization of macrophages, and stimulation of angiogenesis.
